RAMAN SPECTROSCOPY IN ESTIMATING THM FORMATION POTENTIAL IN WATER PIPE NETWORK

摘要

About 250 disinfection by-products (DBPs) have been identified; however, only 20 DBPs including four basic trihalomethanes (chloroform, bromoform, bromodichloromethane, dibromochlo-romethane) are well-known taking into consideration their behavioral profile. There have been made many attempts to predict the occurrence of DBPs in drinking water. The models developed are generally based on the data generated in laboratory scale. However, their practical application in management of water treatment processes and water supply system exploitation seems to be insignificant. Only a few of them have been made in field-scaled investigations. In this paper the results of laboratory studies, including the possibilities of applying a Raman spectroscopy to THMs precursors identification, are presented. Based on the results obtained, the mathematical models describing the level of PTHM potential are constructed.
